In the embodiment, the depot 6 stores a number of to-be-testedPCBs 5. A position of the depot 6 is in a preset position range, which includes a number of sets of coordinates in the Descartes coordinate system. When therobot 2 is within the preset position range, therobot 2 can be considered as grasping a to-be-tested PCB 5 stored in the depot 6 and preparing to carry the grasped to-be-tested PCB 5 to oneopen shielding box 4. In the embodiment, after therobot 2 carries the to-be-testedPCB 5 to theopen shielding box 4, therobot 2 automatically returns to the depot 6. All the predetermined paths form a movement range of therobot 2, and therobot 2 can be controlled to move in the movement range. - Each

block 301, theposition determining module 31 determines the position of therobot 2 at predetermined time interval and determines a set of coordinates of therobot 2 according to the position of therobot 2. Theposition determining module 31 further determines whether the determined set of coordinates of therobot 2 is within the preset position range. If the determined set of coordinates of therobot 2 is within the preset position range, the procedure goes to block 302. If the determined set of coordinates of therobot 2 is not within the preset position range, the procedure repeatsblock 301. - In
block 302, thestate determining module 32 determines whether one ormore shielding boxes 4 are open according to the unique identifiers of the shieldingboxes 4. If one ormore shielding boxes 4 are open, the procedure goes to block 303. - If no
shielding box 4 is open, the procedure repeatsblock 302. - In
block 303, the obtainingmodule 33 obtains the predetermined path of each determinedopen shielding box 4 from thestorage unit 10. - In
block 304, thecontrol module 34 determines a shortest predetermined path among the obtained predetermined paths, and theopen shielding box 4 corresponding to the shortest predetermined path. Thecontrol module 34 transmits a control signal including the determined shortest predetermined path to therobot 2, to control therobot 2 to carry the to-be-tested PCB 5 from the depot 6 to the correspondingopen shielding box 4 and place the to-be-tested PCB 5 into the correspondingopen shielding box 4.

robot 2 and oneopen shielding box 4 is shortest, therobot 2 can be controlled to carry the to-be-tested PCB 5 to the oneopen shielding box 4, thus, the to-be-tested PCBs 5 carried by therobot 2 during the preset time interval increases, which improves working efficiency of therobot 2. - Although the present disclosure has been specifically described on the basis of the exemplary embodiment thereof, the disclosure is not to be construed as being limited thereto. Various changes or modifications may be made to the embodiment without departing from the scope and spirit of the disclosure.
